Subject: [PATCH AUTOSEL 4.14 043/115] i40e: Use proper enum in i40e_ndo_set_vf_link_state

From: Nathan Chancellor <natechancellor@...il.com>

[ Upstream commit 43ade6ad18416b8fd5bb3c9e9789faa666527eec ]

Clang warns when one enumerated type is converted implicitly to another.

drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c:4214:42: warning:
implicit conversion from enumeration type 'enum i40e_aq_link_speed' to
different enumeration type 'enum virtchnl_link_speed'
      [-Wenum-conversion]
                pfe.event_data.link_event.link_speed = I40E_LINK_SPEED_40GB;
                                                     ~ ^~~~~~~~~~~~~~~~~~~~
1 warning generated.

Use the proper enum from virtchnl_link_speed, which has the same value
as I40E_LINK_SPEED_40GB, VIRTCHNL_LINK_SPEED_40GB. This appears to be
missed by commit ff3f4cc267f6 ("virtchnl: finish conversion to virtchnl
interface").
